(1) The Rockwell hardness test is a common method to determine the hardness of metals and polymers using indentation. (2) An indenter applies a minor preload and then a major load, and the hardness number is based on the .Rockwell hardness test is one of the static hardness testing methods using indentation depth as a measuring criterion. Basically, two types of indenter are used; one Diamond spheroconical (Brale) indenter with an angle of 120 O and a spher ical tip of 0.2mm; second is steel ball indenter with diameters as 1/16, 1/8, 1/4, ½ inches. . • The obtained results for the Rockwell hardness test often deviate from the . Conclusions are drawn that the essential differences of the material removal mechanism between hard and brittle .
In conclusion, the Rockwell hardness test serves as an indispensable tool for engineers, researchers, and manufacturers seeking to understand and characterize the mechanical properties of materials.
